Aventurine is quartzite spangled with tiny mica-family platelets — usually green fuchsite — that produce its signature sparkle, aventurescence. Durable (about 6.5–7) and always cheerful, it is a staple of cabochons, beads and carvings, with India as the main source.Our aventurine pieces are natural, individually photographed and certified by the GEMIC Institute laboratory. Every stone is unique; worldwide tracked delivery and our 30-day return policy apply.
